Got new tires last week and the tech smashed and cut the spend sensor wire. Hubs were replaced with Timkens about 3000 miles ago. I replaced the sensor with a new one from AutoZone. Cleared the code and it came back on. Checked code again and it said sensor is missing. I thought maybe it was a bad sensor so exchanged it for a new one. Still same code. Any ideas on what to check now?
ABS light on, says speed sensor is missing, sensor is brand new

i'd redo the repairs on the wires from when they were smashed as you put it.

How does one smash/cut the wires on a speed sensor while changing tires?

Check wiring harness for continuity all the way to the EBCM (Electronic Brake Control Module). Need to know the Year, Make and model to get you the correct wiring diagram. Put it in your signature and you will never have to type it again.

kinda late to this but if you haven’t figured it out yet - here’s the likely culprit ….check the abs wires… there are 2 different wires that are different gauges in size….jack up, take your wheel off , compare with the wire on the opposite side. if the new one is smaller or larger than the one that wasn’t replaced - that’s the issue. one is for AWD - one is for 4x4….it’s very easy to wind up with the wrong one & very hard to know so when you’re buying it. as many parts that are 4x4 are also compatible AWD…. check that. if they differ - replace it with the correct one & should fix your issues
i just replaced my hub & had the same issue. i always keep my old parts in my garage for this reason - i jacked my truck back up, swapped it out with the one from my old hub & it took care of the issue. the sensor on the end of the wire that fits into the hub is the same size. as is the electrical terminal . the wire itself is the only part that will be different.
